I'm sorry, but I have to ask why one would use PVC for ones fids?
The chemical make up of PVC could be fatal to the birds.

Phthalates
Polyvinyl Chloride (PVC, or Vinyl) is one of the most commonly used materials in the consumer marketplace. We find it in packaging, construction and automotive material, and in a wide varieyy of consumer products, including toys and medical equipment. PVC contains Phthalates, which accumulate in body tissues, and can damage liver, lungs, and have been shown in lower mammals to damage reproductive organs. Phthalates are freely given off by plastics in which they occur. Because they are fat soluble, they are found in quantity in meats and cheeses wrapped in PVC packaging. Although Phthalates show almost no toxicity in adult humans in acute (short term) doses, even at high doses, the cumulative nature of phthalate toxicity results in toxic effects even at very low dosage when ingested chronically (over a long period of time). Very young infants may be at greater risk of harm, especially to the male reproductive system. The common availability of Phthalates in the consumer environment causes inevitable chronic ingestion for almost all modern industrial consumers. [More detail]
Lead
A minority of popular mass-market children's products have been found to contain lead. The lead becomes available as dust on the product surface as the product ages. Lead is a cumulative poison, is stored in bone, and results in irreversible nervous system damage when ingested by young children, particularly ages 1 to 3. Extremely low blood levels have been reliably correlated with behavioral deficits in humans, as well as biochemical changes. No level of chronic lead intake may be regarded as safe for children. [Details]
It is not obvious from the product or packaging which PVC juvenile products contain lead and which do not. In fact, it is not always easy to tell by looking which plastic products are made of PVC. There is tendency of manufacturers to resist efforts to obtain this information.
Recommendations
For these reasons, we recommend that toys or other items containing Vinyl not be used for children under three years of age, during which period children tend to mouth or chew non-food objects. Further, we recommend that consumers attempt to ascertain which PVC products used for older children, or, for that matter, present in the home environment, contain lead, and dispose of those items.

Lead stabilisers (mainly lead sulphate) are added to PVC compounds in order to prevent degradation from heat and light, and to improve processing properties.
Lead as health hazard and environmental poison
It accumulates within the body, and can damage the nervous system, kidneys and blood formation. It is also very poisonous to aquatic organisms. Much international effort has been made during recent decades, to reduce or eliminate the used of lead in many applications. Perhaps best known is the switch to lead-free petrol, which has removed the greatest lead pollution source. Programmes exist today for the removal of lead compounds from many applications; amongst them lead stabilisers used in PVC compounds. Lead stabilisers constituted 3% of the total European lead consumption during 1995.

Now the way I see it is if PVC is hazardous to my new grandson, who weighs in now at 16 pounds (7257.478 gms), it sure as heck has to be even more hazardous and surely fatal to my 95 gram tiel Sydney.
